Overview
A tiny flash of rainbow is the centerpiece of this gold-toned bar brooch, with an apparently opal cabochon framed by an open, four-lobed motif. The fitted Belfast retailer's case adds a wonderful local connection, although it does not establish who made the brooch or whether the case is original to it.
Story
Around 1900, a slim bar brooch could secure a lace collar while adding a discreet jewel. This one's Belfast case connects that intimate fashion accessory to the city's bustling commercial heart, Donegall Place.
Maker / Origin
The readable case names Gibson & Co. Ltd., Goldsmiths, of Donegall Place, Belfast, beneath a 'By Appointment' crest. Retail jewelers often sold work supplied by specialist workshops, so this is evidence of a retail connection rather than a confirmed manufacturing attribution.
Condition & Value
The metal shows surface scratches and darkening, while the case has edge wear and discoloration to its lining. No obvious major stone loss is visible, but the photographs cannot exclude fine cracks; stone integrity and a working clasp materially affect value.
